Violations of personal rights have soared over the past six years in Mexico, with more than 2,000 people listed as missing and over 46,000 murders linked to organized crime groups, the Mexican National Human Rights Commission, or CNDH, said.

The Senate should address the problem of security "with the greatest urgency" in Mexico, where just eight of every 100 crimes committed are reported and only 1 percent of crimes are investigated by prosecutors, allowing 99 percent of crimes to go unpunished, CNDH chairman Raul Plascencia said.

The CNDH has opened cases on 2,126 forced disappearances over the past six years, as well as tallying 46,015 killings linked to the wave of drug-related violence in the country, 15,921 unidentified bodies and 1,421 bodies discovered in clandestine graves, Plascencia said.

The CNDH, Mexico's equivalent of an ombudsman's office, has received 34,385 complaints against federal security officials since 2005, with torture being the top problem, Plascencia said.

While only one complaint was received for torture in 2005, a total of 2,040 complaints of cruel, inhuman or degrading treatment were registered last year, the CNDH chairman said.
